PRODUCT DESCRIPTION

FRP rods and tubes are manufactured by high-strength fiberglass as reinforcing material, thermosetting resin as the base, and then taken shape on a special pultruded mold, where the high temperature activates the resin to cure.

Pultruded grating is made by a particular assembly process, which using “I” shape as its main load-bearing and special rod to go through the bearing bar. Pultruded grating include the standard grating and the custom grating, the custom grating can be designed to meet customer’s requirement or special using condition by changing the shape, size and space of the bearing bars, the surface can be covered with lozenge panel, grit panel, or added the anti-slippery sand directly.
FRP pultruded grating has the most characteristics of molded grating, but it has its distinct advantages, it has very high fiberglass content in the loading direction, so it has very high load capability, it has more superiority when used at wide span, so that the basic support will be decreased and the project cost will be reduced accordingly.

FEATURES

1.  High anti-corrosion capability, long designed service time of 20 years;
2.  Good hydraulic property, smooth inner surface with absolute roughness of 0.01mm, which is far less than that of carbon steel pipe or cast iron pipe;
3.  Lightweight and facility to install and transport;
4.  High specific intensity and reliable mechanical performance;
5.  Low thermo-conductivity and small thermo-stress, which are allowed to be used in various conditions: exposed buried or suspended, in ocean or in deserts, freezing or humid;
